-9 Claims.

This invention relates to means for stripping unused rovings fromskewers such as used in spinning frames and indisintegrating the rovingsinto a mass 01' disconnected fibers so that such fibers can beimmediately transferred to the picking room and passed through thepickers along with other fibers coming from the opening room.

It is a well-known fact that in spinning rooms,

that when nearly all of the roving has been withdrawn from the tubedisposed on the skewers in the spinning frame, that these are castaside, and it is necessary to remove these unused rovings from the tubesbefore the tubes can be used again. Furthermore, it is desired torecover the fibers i'rom these unused portions, and heretofore thepractice has been to pass a sharp knife longitudinally of the tubes tosever the various convolutions oi! rovings to quickly remove them fromthe tubes. This has resulted not only in injury to the tubes, but alsoin a shortening of the fibers because long fibers are cut in thisoperation, and when the cut fibers are passed back to the opening roomand the rovings reprocessed to pass them through a picker to preparewebs of fibers, there is much loss on account of the short fibers beinglost during the processing operation.

It is an object of the present invention to provide means forwithdrawing the unused portions of rovings from the tubes on skewers andthe like and disintegrating the fibers as they are withdrawn and thuspreserving the fibers in their original staple length without any injurywhatever to the same. Some of the objects of the invention having beenstated, other objects will appear as the description proceeds, whentaken in connection with the accompanying drawings, in which 2 containerhas screens l3 and H at each end thereof, and has a preferably circularopening l5 over which a suitable lid, not shown, may be placed and overwhich a bag can be placed for receiving the fibers within the box orcontainer Ill. The container Ill has a lid i6 hingedly secured as at I!to one of the side walls of the box Ill. The lid l6 has a tubular memberin penetrating the central top portion thereof near one end and has aplurality 01 supporting stands 22 and 23 in which is mounted a pipe 24having a cut-off valve 25 therein and the pipe 24 is adapted to besecured by means of a clamp 26 to a flexible air hose 2! connected to asuitable source of compressed air, not-shown. The pipe 24 has adownwardly projecting restricted elbow 3.0 on its free end whichprojects down into the tubular member 23.

Figure 2 is a side elevation looking from the lower side of Figure 1with portions broken away;

Figure 3 is an end view looking from the righthand side 01' Figures 1and 2;

Figure 4 is a vertical sectional view taken along the line 4-4 in Figure3;

Figure 5'is a view similar to the right-hand end of Figure 2, butshowing a modified form of the invention Figure 6 is an enlargedsectional along the line 6-8 in Figure 2;

Figure 7 is an enlarged vertical sectional view of the top centerportion of Figure 2.

Referring more specifically to the drawings, the numeral ill indicates acontainer, preferably of rectangular shape and having wheels I I. The

plan view taken Mounted in the top of lid portion It: and near' one endthereof is a plurality of spaced porcelain supports 33, each adapted toreceive the lower pointed end 34 of a skewer 35. c The skewers 35 arevertically arranged and the upper ends of these skewers are restrictedas at 36 and these restricted portions are adapted to penetrate suitableholes 31 in a horizontally disposed board 38 which is supported neareach end thereof by means of vertical supports 40 and 4|. These skewerseach have a tube 43 fitted thereon, and

said tubes 43 before being fitted or slipped onto the skewers 35 havewound thereon a plurality of Y convolutions of rovings 44. These rovingsare wound onto a cross-sectional diameter of several inches and theserovings are led from the skewers and tubes through a spinning frameapparatus.

When nearly all of the rovings are exhausted from a skewer or tubethereon, the same is removed. In the present embodiment of thisinvention, these skewers 35 with the tubes 43 thereon are arranged inthe plurality of supports 3.3 as shown in the drawings, and one at atime, an end is withdrawn from the skewers and is passed down around therestricted tube 3| where a blast Y of compressed air not only withdrawsthe roving 44 from the tube 43 but also disintegrates the flbersof theroving and converts these fibers into a fiuffy mass. When it is desiredto remove the fibers from the container in, the lid Hi may be raisedupwardly and the operator may guide the fibers out through the openingI5 into a bag secured around the annular rim l5.

Or if desired, instead of letting the disintegrated rovings fall intothe container l0, there may be provided an arcuate tube 50 which will besecured to the lower surface of the lid I8 and surround the tube 20,and. the rovings as they are withdrawn from the tubes 43 will bedisintegrated by the let of air and will be iorced loosely by the blastsof air along tube I and out the lower end thereof where a suitable bagcan be disposed over the right-hand end of the tube 50 in Figure 5, orif desired. a suitable pipe can be connected to this tube 00, and thefibers can be carried by suction or otherwise to any desired art of themill such as the opening room or the icker room where they will bereprocessed.

The rate of feed of the roving N from a skewer 48 is regulatedby thesharpness of the pointed lower end or the skewer. If the roving ieedstoo fast, the lower pointed end of the skewer can be flattened to thuscause the skewer to present more friction or drag to its rotation. I

The suction of air around the compressed air nozzle 30 does not take anyappreciable twist out of the roving, but when the roving comes incontact with the blast of air from the nozzle, the roving isdisintegrated.

The jet of compressed air from the nozzle 30 creates inwardly moving aircurrents around the nozzle and serves to feed the roving past the nozzle30.

ployed, they are used in a generic and descriptive sense only, and notfor purposes of limitation, the scope of the invention being defined 'inthe claims. a

I claim:
